About These Birds
Anna's Hummingbird
Anna's hummingbird is the most common hummingbird along the Pacific coast and one of only three species resident in the United States year-round. Males perform spectacular dive displays, plummeting from 40 meters and pulling up with a loud chirp produced by tail feathers. Their body temperature can drop to near ambient at night to conserve energy.
Blue-throated Mountain-gem
O beija-flor-de-garganta-azul é o maior beija-flor dos Estados Unidos, com garganta azul brilhante nos machos, encontrado em cânions e montanhas do sudoeste dos EUA e México.
